 a ratchet which regulates rotation of the latch; 
 a detecting sensor including a body, at least two terminals exposed from the body, with signal cables being connected to the terminals, the detecting sensor being configured to detect operation of the latch or the ratchet; 
 a main body in which the detecting sensor is arranged, the main body including
 a discharging hole at a position in an area between the terminals of the detecting sensor, at least one of the two terminals of the detecting sensor being arranged on an upper side of the vehicle above the discharging hole in a state in which the door is closed, and 
 a rib separating and parallel to the two terminals, wherein the rib projects from the discharging hole, 
 
 wherein the discharging hole is formed so as to extend from the body of the detecting sensor toward a side of the terminals, 
 wherein the detecting sensor is arranged so as to abut the rib, and 
 wherein the discharging hole is configured to discharge at least one of water entering through the signal cables and water separated by the rib. 
 
     
     
       2. The latch device for a vehicle according to  claim 1 , wherein the rib is substantially between the terminals. 
     
     
       3. The latch device for a vehicle according to  claim 1 ,
 wherein the main body includes a surface on which the detecting sensor is arranged, and 
 wherein the latch and the ratchet are arranged on a side opposite to the detecting sensor on another surface of the main body. 
 
     
     
       4. The latch device for a vehicle according to  claim 1 ,
 wherein the door is a tailgate of the vehicle, and 
 wherein the latch is configured to mesh with the striker so as to maintain a closed state of the tailgate. 
 
     
     
       5. The latch device for a vehicle according to  claim 1 , wherein the latch comprises:
 a meshing groove configured to mesh with a groove of the striker, 
 a hook portion disposed laterally to the meshing groove so as to be on a first side from the meshing groove, and 
 an abutment portion disposed laterally to the meshing groove so as to be on a second side of the meshing groove. 
 
     
     
       6. A latch device for a vehicle provided on a door of the vehicle, comprising:
 a latch configured to mesh with a striker; 
 a ratchet which regulates rotation of the latch; 
 a detecting sensor including a body, at least two terminals exposed from the body, with signal cables being connected to the terminals, the detecting sensor being configured to detect operation of the latch or the ratchet; and 
 a main body in which the detecting sensor is arranged, and including a rib separating the two terminals and projecting from a discharging hole configured to discharge water, 
 wherein the discharging hole is disposed at a position in an area between the terminals of the detecting sensor, and formed so as to extend from the body of the detecting sensor toward a side of the terminals, 
 wherein at least one of the two terminals of the detecting sensor is arranged on an upstream side of the discharging hole with respect to a flow of the water, 
 wherein the detecting sensor is arranged so as to abut the rib, 
 wherein the discharging hole is configured to discharge at least one of water entering through the signal cables and water separated by the rib, and 
 wherein ends of the terminals are parallel to and spaced apart by the rib. 
 
     
     
       7. The latch device for a vehicle according to  claim 6 ,
 wherein the door is a tailgate of the vehicle, and 
 wherein the latch is configured to mesh with the striker so as to maintain a closed state of the tailgate. 
 
     
     
       8. The latch device for a vehicle according to  claim 6 , wherein the latch comprises:
 a meshing groove configured to mesh with a groove of the striker, 
 a hook portion disposed laterally to the meshing groove so as to be on a first side from the meshing groove, and 
 an abutment portion disposed laterally to the meshing groove so as to be on a second side of the meshing groove. 
 
     
     
       9. A latch device for a vehicle provided on a door of the vehicle, comprising:
 a latch configured to mesh with a striker; 
 a ratchet which regulates rotation of the latch; 
 a detecting sensor including a body, at least two terminals exposed from the body, with signal cables being connected to the terminals, the detecting sensor being configured to detect operation of the latch or the ratchet; 
 a main body in which the detecting sensor is arranged, the main body including
 a discharging hole at a position in an area between the terminals of the detecting sensor, at least one of the two terminals of the detecting sensor being arranged on an upper side of the vehicle above the discharging hole in a state in which the door is closed, and 
 a rib separating and parallel to the two terminals, wherein the rib projects from the discharging hole, 
 
 wherein the discharging hole is formed so as to extend from the body of the detecting sensor toward a side of the terminals, 
 wherein the detecting sensor is arranged so as to abut the rib, and 
 wherein the discharging hole is configured to discharge at least one of water entering through the signal cables and water separated by the rib, such that the water is not accumulated between the terminals.
